Nutanix NCP-CI-AWS Nutanix Certified Professional - Cloud Integration - AWS v6.7 Exam Practice Test

Answer : B

In Nutanix Cloud Integration with AWS, specifically version 6.7, the role that allows full access to clusters created within an organization is the Organization Administrator.

The Organization Administrator role has the highest level of privileges within an organization, enabling the user to manage all aspects of the clusters, including creation, modification, and deletion.

This role is designed to oversee and control the entire organization's resources, ensuring comprehensive management capabilities over all clusters and associated resources.

Reference: Refer to the Nutanix documentation on roles and permissions for NC2 on AWS for further details.

Answer : C, D

To ensure that NC2 VMs can access AWS resources without traversing the internet, the administrator can use AWS VPC Peering and Interface Endpoints. Both methods ensure that traffic stays within the AWS network, maintaining security and efficiency.

Interface Endpoint:

Interface Endpoints allow you to privately connect your VPC to supported AWS services. They use AWS PrivateLink to route traffic directly to services within the AWS network, bypassing the public internet.

Steps:

Create an interface endpoint for the required service in the AWS VPC console.

Ensure the security groups and route tables are configured to allow traffic to the interface endpoint.

VPC Peering:

VPC Peering allows the routing of traffic between VPCs using private IP addresses, without the need for internet gateways, NAT devices, or VPN connections.

Steps:

Create a VPC peering connection between the VPCs.

Update the route tables to direct traffic between the peered VPCs.

Ensure security group rules allow the necessary traffic between VPCs.

Answer : B

The role of 'Customer Administrator' in Nutanix Cloud Integration with AWS (NC2) is designed to meet the requirements of creating and managing multiple organizations and clusters, as well as managing user access for the entire company.

Roles and Permissions:

Customer Administrator: This role has the broadest set of permissions, allowing the user to create and manage organizations, clusters, and user access across the entire company. It encompasses administrative control over multiple aspects of the NC2 environment.

Capabilities:

Organization Management: Ability to create and manage multiple organizations.

Cluster Management: Full control over creating, configuring, and managing clusters.

User Access Management: Manage user roles and permissions, ensuring that the right individuals have access to the necessary resources.

Why Not Other Roles:

Organization Administrator: Limited to managing organizations but not clusters and user access at the company level.

Customer Security Administrator: Focuses on security aspects, lacking broader administrative capabilities.

Cluster Administrator: Limited to managing clusters without the ability to manage organizations and user access comprehensively.

Answer : D

When creating user VM subnets for multiple NC2 clusters in AWS, the best approach is to create guest-VM subnets for each cluster. This ensures that each cluster has its own dedicated subnets, which simplifies network management and avoids potential IP conflicts.

Advantages of Dedicated Subnets:

Isolation: Each cluster operates in its own subnet, providing better isolation and security.

Management: Easier to manage and troubleshoot network issues when each cluster has its own subnets.

Scalability: More scalable as each subnet can be managed and expanded independently.

Steps to Create Guest-VM Subnets:

Identify the IP range for each subnet.

In the AWS VPC console, create a new subnet for each cluster using the identified IP ranges.

Associate the new subnets with the respective clusters during or after the cluster deployment process.

Why Not Shared Subnets:

Shared subnets could lead to IP conflicts and make network management more complex, especially as the number of clusters grows.

For a new NC2 on AWS deployment where workload VMs have low storage and memory requirements but high CPU frequency (>3.0 GHz) requirements, and the goal is to minimize the number of CPU cores to reduce application licensing costs, the i3.metal instance type is the most suitable.

i3.metal:

High CPU Frequency: i3.metal instances offer high-frequency Intel Xeon processors (up to 3.1 GHz) which meet the high CPU frequency requirement.

Low Storage and Memory: These instances come with a balanced amount of storage and memory, suitable for workloads with low requirements in these areas.

Minimized CPU Cores: i3.metal instances have fewer CPU cores compared to other high-frequency instances like i4i.metal, making them ideal for minimizing application licensing costs.

Other Instance Types:

z1d.metal: While also offering high CPU frequency, these instances typically come with a higher core count and more memory, which may not be optimal for minimizing licensing costs.

i4i.metal: Designed for I/O intensive applications with higher core counts.

m5d.metal: Balanced instance type but with more cores and not as high CPU frequency as required.
